BEATER FOR USE IN MACHINES FOR OPENING COTTON.

SPECIFICATION forming part of Letters Patent No. 524,695, dated August14, 1894.

Application filed March 30, 1894:- Serial No. 505,752. (No model.)

To all whom it may concern:

Be it known that 1, JAMES (J. POTTER, residing in Pawtucket, in theState of Rhode Island, have invented a new and useful ImprovementinBeaters for Use in Machines for Opening Cotton and other FibrousMaterials, of which the following is a specification.

The opener-beater to which my invention relates is one that is armedwith projecting pins or studs which strike the cotton or other malterialas it passes from between the feed ro s.

It is my object to produce a beater of this kind that shall do efficientwork without injury to the staple, and shall be very durable.

The nature of my invention and the manner in which the same is or may becarried into effect can best be explained and understood by reference tothe accompanying draw ings, in which- Figure 1 is a front elevation of abeater embodying my invention in its preferred form. Fig. 2 is an endelevation partly in section of one of the sections of which the beateris com posed, with a diagrammatic representation of the feed rolls inorder to indicate more clearly the relation in which the pins stand tothem, when the beater is mounted in an opening machine or scutcher. Fig.3 is a section through one of the bosses on line 3-3, Fig. 2,

The pins A which project from the body or shell of the beater and areset staggering are cylindrical in cross section. They present a halfround surface to the cotton when doing their work, thus avoiding thesharp corners which are found in square or like shaped pins, and whichare apt to curl or string (as it is termed) the cotton. The pins are notradial but are set oif at an angle as represented in the drawings-thatis to say they are set at such an angle as to intersect the prolongationof the diameter of the beater, with their outer ends inclined slightlyrearwardly relatively to the direction of revolution of the beater, asindicated in Fig. 2. When thus set they present a keen half roundworking edge to the cotton passing from between the feed rolls X. Thepins are held in tubular bosses B, which are set at the proper angle togive the pins the requisite rearward inclination and are of lessinternal diameter than the projecting parts of the pins, whose shanksare turned down to fit in the bosses. The pins are held in place by nuts0, on the screw threaded inner ends of their shanks which draw theshoulders on the pins tightly down on the bosses, split colters I) beingput through holes in these ends to prevent the nuts from working off.

In working on the cotton the portion of the edge of the pin which meetsthe cotton becomes dull and worn off, so that it will not do its workproperly. To obviate this difiition of the edge of the pin can bepresented to the cotton whenever desired.

The outer portion or end of each tubular boss has internal radialgrooves or recesses c, which receive one or more lateral projections orstuds (1 on the shank of the pin. Whenever the portion of the edge ofthe pin presented to the cotton becomes worn, and it is desired topresent a new keen edge, the nut a is loosened, the pin is drawn out ofits boss far enough to disengage the projections d from the recesses c,is given a quarter turn, to present a fresh portion of the edge, and isthen dropped back and secured in place. The same result can be securedin other ways as for example by having a squared or equivalently formedshank for the pin, and asocket of corresponding shape in the boss. Inthis way the life of the heater is much prolonged; and the pinsthemselves last four times as long as they would were they not madecapable of the adjustment just described.

I prefer to make the beater a sectional one, its body being composed ofsections 0, each being a single spider casting having a cylindricalshell with bosses for the pins, a hub and arms connecting the hub andshell as seen in Fig. 2. These sections are keyed on the shaft D, asindicated at X and are held together thereon by end nuts E.

inch in diameter; the bosses are bored out to three-fourths of an inchinternal diameter; and the shanks of the pins are turned down tothree-fourths of an inch to fit the bosses.

Having described my invention and the culty I provide means whereby afresh por- In practice the pins are seven-eighths of an 5 best way nowknown to me of carrying the bosses in which said pins fitand are capablesame into effect, what I claim, and desire to of individual axiallyrotary adjustment, and

secure by Letters Patent, is as follows:

' 1. In an opener-beaterthe combination with tubular rearwardly inclinedbosses provided with radial internal grooves or recesses, of

' cylindrical pins fitting said bosses and provided with lateralprojections entering said grooves or recesses, as and for the purposesset forth.

2. An opener-beater having rearwardly incllned cyhndrical pins,similarly inclined means for holding thepius in their adjusted 15position, as set forth.

In testimony whereof I have hereunto set my hand, before two subscribingwitnesses, this 28th day of lVIarch, 1894.
